The only real failure in life is not to be true to the best one knows.

Outward failure may be a manifested variant of inward success.

Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.

My great concern is not whether you have failed, but whether you are content with your failure.

We climb to heaven most often on the ruins of our cherished plans, finding our failures were successes.

Our failings sometimes bind us to one another as closely as could virtue itself.

I can accept failure, everyone fails at something. But I can't accept not trying.

You can't be afraid of failure and you can't be afraid of success, because either one gets in the way of your work.

Failure is more frequently from want of energy than want of capital.

Do not fear mistakes. You will know failure. Continue to reach out.
